10k likely wouldnt go very far, so I'd probably go for (shoot me?) a good quality virtual pin, couple decent multi-arcade machines, one nicer real machine and a few nice EM's or SS. I know a virtual pin isnt going to play the same but the variety is cool, also good for getting more familiar with machines I'd look to pick up later. I'd also pick up a foosball table, good stuff for 2-4 players.
